One person washes their hands compulsively to feel some sense of cleanness. One person sits in the shower for 45 minutes after being defiled by another person trying to feel clean. One person drinks to forget their guilt. One person erases any standard in their life so they won’t feel guilt. One person cuts themself to experience relief from their anger and shame. One person tries to re-invent themselves to get away from their shame.
Different actions but what they all are doing is dealing with sin. We all create rituals or processes to address the guilt, defilement, and shame, from our sin and others’ sin against us. You may not think sin is a real thing. But your actions show you functionally think it is real because you try to address it—even if that means ignoring it.
